| Abstract: | Against the given agricultural requirements of maize no-tillage planter, expound the principles of design and ideas of the suction maize no-tillage planter, introduce its design features and technical parameters,and make a mention of rational working parameters about ground-working opener. Field capabilities experiments indicate that mean depth of fertilizer application is 87mm, mean depth of planting is 52mm, percent of pass of spacing in the row is 96.8%, the space length between seeds and fertilizer cutting stubble, opening, fertilizing, seeding, earth covering and compacting and so on. It makes the destabilization of soil less and caters the requirements of planting qualities of high-speed and precision. |
